Most powerful Rotax engine

[DrewNJ]

.
I was wondering the exact same thing. Bet it would be bear to cool it on a byke! But, if you could, what a ryde!

It uses antifreeze and a heat exchanger in the ride plate to act as a radiator to cool the motor. Only fresh water to cool the exhaust.

That is a marine motor. Same issue as with the 255HP skidoo motors.... They produce that power but you have to remember that they use fresh cool water from lakes/oceans/etc to cool the engine... Something that would be very difficult to do on a Spyder without adding a bunch more cooling.

I don't think that is true anymore they use closed loop cooling systems on the newer skis thus eleminating the moss plugging of the tubing and the salt corrosive issues

Yep, been closed loop since 2003 when they first went to the 4-tec.

Hmmmm......I think that in order to increase the power to that extent will need at
least a tougher clutch, output shaft bearings and final drive bearings on the primary and rear pulleys.
I wouldn't want to put that sort of available grunt through the standard gearbox either. Just my twopence worth!

It's soooo pretty :shocked:

Yup! And since you'll have WAYYYYY.... too much power to put to the pavement effectively: Nanny won't let you ride any faster, than you do right now... :banghead:

You'll need a gearbox too. The setup off the seadoo's is direct drive.


Bob D, you can NEVER have to much power...[emoji38] [emoji106]

But you can very easily have too much, to get hooked-up and useful! :clap:

BRP state this is their most powerful Rotax engine
1630 ACE ENGINESupercharged with an external intercooler, the Advanced Combustion EfficiencyAC)technologydelivers high effic amazing acceleration. This is the most powerful engine on a Sea-Doo, ever

Although they use it in their Sea-Doo, Wonder if we will ever see this in a Spyder

looks badass:firstplace:

Although the cost of adding the transmission could slow things down and the space needed. They do have the lower hp models they could offer at least in the V-twin's like the ones used by aprilla motorcycles (140+)...Sadly I am past the "wanting more horsepower than I could ever use" stage...:roflblack:

Agree, seems BRP would have to rebuild a platform to accommodate this beast of a motor, and what to do with all that energy and torque? Bigger fuel tank?

For everyday driving, that much power can be hard to control. Just with my stage one flash, the throttle has gotten a little touchy at times.

Very few marine engines use raw water cooling any more since it rusts out the engine from the inside out when used in salt water. But I think a water to water intercooler would be more efficient than an air to water one, so it's very likely a much larger cooling system would be needed.

I have a buddy that has Slingshot … He is a mechanic, and bought a HAAN Turbo …. At speed, in third gear He could spin the rear tire at will ….. He up-graded to an aftermarket wheel and rear Fork to house a 375 / 35 tire …. He can still break it loose at will …. just sayin …. Mike hyea:

i asked my dealer, HUNTER MOTORSPORTS of Hendersonvlle, NC if that engine could be installed in my 2019 F3... the Service Manager/Lead Technician, Lang, told me that the existing engine and the 300 HP engine are so different, that it would be literally impossible to make the change... of course, if you drop enuff USD, anything is possible...
just say'n....

You have to love it when a OLD POST get's every body's mouth watering, again!!!:roflblack:

Neither my ‘20 RTL nor my ‘20 900 ACE have any difficulty achieving the posted speed limit.

But the thought of more power has been out there for many of us. :bowdown:

 

[troop]

Very content with my current F3S. That said, my wife already knows that any updates/upsizing in the power train department will have me shopping. Also if Honda EVER releases the NeoWing (but that topic has been covered extensively)

If they were to make some thing with a shaft drive, and make it handle as good as the spyder I think that would be good for the market! I would kick the tires a little! I mean after all, you know they watch this forum, and they get the letters and calls to fix these issues that we have and for the most part they shrug us off, it feels like. Don't take this the wrong way, I love my ride, but for the money for a new one, I would like to see some of the issues that we have, go away!!!! They made some great body style changes, that's great, the suspension could be looked at, get rid, or make that auto air ride, more dependable, or do away with it, I like a good shock system myself! Competition is a good thing, it keeps every one in the hunt, and sharp!!hyea:
